NEUMATIC-RUBBER-TUBE AND METAL-.STEM PROTECTOR.

Specification of Letters Patent.

Patented Apr. 14, 1914.

Application filed December 1, 1913. Serial No. 804,110.,

lo alZ 'whom 'it may Con-cern Be it known that I, JAMES M MAJoRs, acitizen of the UnitedStates, residing at Ottumwa, in the county ofWapello and State of lowa, have invented a' certain new and usefulPneuni'atic-Rubber-Tube and Metal- Stem Protector, of which thefollowing is a specification.

The object of my invention is to provide a pneumatic rubber tube andmetal stemprotector, of simple, durable and inexpeir' tact with partswhich would injure the threads, or the like, and from contact, with therubber tube. Y

A further object is to provide a device of the kind just mentioned soarranged that the stem protecting part is mounted within the waterproofcasing suitably adapted to contain the rubber tube.

My invention consists in certain details,

-in the construction, arrangement and combination of the various partsof the device, wherebythe objects contemplatedare attained, ashereinafter more fully set forth, pointed out in my claims, andillustrated in the accompanying drawings, in which:

Figure 1 shows a plan/'view of a pneu matic rubber tube andmetal stemprotector embodying my invention as the same is laid out before the tubeis placed in it. Fig. 2 shows a top or pla-n view of the rigid stemholding and supporting member. Fig. 3 shows a transverse, vertical,sectional view of the device 'after the stem has been placed in positionand the tube folded and the side members of the casing have been foldedover. Fig. 4 shows a vertical, sectional view 'taken on the line 4 4 ofFig. 3, and Fig.

5 shows a plan view of the device wrapped into a bundle with the tubeinclosed therein.

My improved device comprises a sheet of waterproofing material which lhave indicated in the accompanying drawings by the reference numeral 10,and which is prefer# ably rectangular in shape, as shown in Fig. 1.Sewed, or otherwise secured to the side l edges of the sheet 10vadjacent to one end thereofg'are side wings 1-1 of similar waterproofmaterial. l ,Secured to the strip 10, preferably approximately betweenthe upper .rends of the wings 11, is a flap '12. 'vlhe flap ,.12ispr'eferably secured along its upper edge,

as shown in Fig. 1, so that the llower-portion thereof is free to move.Arranged longitudinally of the flap 12, adjacent to one.

end ofthe portionfthereof which is free to move', and preferably nearthe edge of the strip v10, as 'shown by the dotted lines in Fig. 1, andincross section in Fig. 3, is'a rigid metallic tube supporting member13. VThe end of the member 13, adjacent to the neares t edge of thestrip 10, as shown at B in Fig. 3, is thicker than the other endof saidmember 13,.v as clearly shown in said tigure. Extending longitudinallythrough the thicker portion of theend B of the member 13 is an openingli'designed to receive the stem-15 of an inner tube. ,The opening 14 isso located that the free end of the tube,

' when inserted in said opening, ifl long enough, will extend throughthe opening and rest just above the thinner end of the member 13, asclearly shown in Fig. 3.

Secured to the upper ysurface of the thick end B of the member 13v is aspring device which may be made of two parallel flat springs 16 whichextend beyond the thick portion B to points above the thinner end of themember 13. The free ends of the springs 1G form bearings 17 for a smallshaft 1S on which, between the springs 16, is mounted a rubber roller19. IThe roller 19 extends down to a point slightly below the level ofthe upper part of the hole or opening 14 and is adjacent to the thickportion B of the meniber 13, and is designed to yieldingly engage thefree end of the stem 15, as shown in Fig3.

Secured to the flap 12, and covering the rigid supporting device 13, isa second flap 20 which is fastened only adjacent to its end near thethick portion B so that its other end is free to be raised or folded out.of the way.

ln the practical use of my improved device. the flaps 12 and 20, and therigid supporting device 13 are raised slightly and the stem 15 of aninner tube 21 is inserted in the opening 14 withA its free endprojecting through said opening above the thinner part of the niember13.One portion of the tube 21 is then extended under the flap 12 and theother portion is extended over the flap and the remainder of the tube isthen folded into coils, as shown in Fig. 3. The wings 1l are then foldedover the folded tube 21, and the lower and upper'parts of the strip 10are folded over and the bundle thus formed may be tied with theflexibledevices 22, forming a comparatively small and compact package.

The strip andthe Wings 11 being made of waterproofl material willprotect the rubber from contact with oil or moisture, thereby thoroughlyprotecting it. The construction and arrangement of the rigid supportingdevice 13 is such that the metal stem 'is firmly supported and isyieldingly held against rotation and against removal by the.

rubber roller 19.

The portion B is preferably of such thick# ness that the curved metalshield 23, `found on the ordinary inner tube, extends only a shortdistancev above and below it so that there is littlev likelihood of thetube being cut on said metal part. c

The stem 15 may rotate in the opening 14 slightly for adjust-ing theparts vin position and on that account it is not likely that the rubberwill be torn in placing the tube in the casing. The tube, when placed inmy casing, can be put in the ordinar toolbox or in any convenient place,and wi l be safe from contact with metal tools'or hard parts which mightotherwise bruise or injure it. The

tube can be readily folded intov a comparatively-small space and can beWrapped ,so that the rubber practically does notchfe or rub.

It may be noted that by placing the stem `tube during the process offolding.

It is understood that numerous changes may be made in the details of theconstruction of my device without departing fromits essential featuresand it is my intention to cover by this application any such changeswhich Vmay be included within the scope of the appended claims.

I claim as my invention:

k A 1. In a device of the class described, a

flexible Waterproof casing, vazrigid supporting device, flexibly securedthereto, having a thickened end provided with an opening extendingthrough it to receive the stem of a rubber tube so that the stem mayprojectl above the thinner portion of said supporting device, and anon-metallic device for yieldingly engaging'the free end of said stem.

2. In a device'of the class described, a flexible Waterproof covering, aflap secured thereto along one edge, a rigid supporting device securedto the loose portion of said flap near one edge thereof, saidsup-porting device having a thickened end provided with a `longitudinalopening to receive the stem of an inner tube, a non-metallic yieldingdevice arranged to engageI the end 'of said stem, and a second flaparranged to cover said ri id supporting device.
